	// contains filtered or unexported fields
}

Runner runs a goroutine and cancels the context of any previous call to run.

func New

func New() *Runner

func (*Runner) Go

func (r *Runner) Go(ctx context.Context, fn func(ctx context.Context))

Go cancels the context of the currently running goroutine (if any) and runs fn in a new goroutine without waiting for the previous to return.
